Be careful.  You will have to deal with possibilities like the objects 
being deleted since you ran your original query.

Even if you have the live objects index enabled, this will result in a 
fresh fetch from the database:

my $artist = Artist->retrieve($id);
undef $artist;
$artist = Artist->retrieve($id); # back to the db

There is also a private method called _attribute_delete() which can 
remove specific columns from an object so that they have to be re-fetched.
